III. Comments - Compliance
Below are comments on the inspection. The comments include discussion of
observations made during the inspection. Comments also describe any
enforcement actions taken during the inpsection and the facts or evidence
supporting the enforcement action.
On September 28, 1989, Cathy Begej performed a Phase I bond release inspection
of the Bourg Mine. Mr. Walt Ayres, a representative of Walden Coal Company
attended the inspection. Landowners were notified of the inspection. Wone
attended. Included in this inspection r^eport is a photo journal, a log of
inslope readings on selected terrace di•:ches and a field map documenting the
location of the 198+ and 198;1 reclaim areas tithe approximate location of
the settlement cracks and the location of tie contour terrace benches.
~pe Bourg t41ne pernrit area covers 160 arses. The gently sloping hill within
Ne property has a predominant west-northwest aspect and an average grade of
6.5X,~rades at the site vary from 2.6i,'to 14.4X. Three reclamation profiles
were run on the property ranging in len!Ith from 820' to 1700'. The maximum
hydraulic length on the property runs fr^om the low area on the southeast
corner of the property to Mann Draw and is 3800' long.
The topo9rapliy at the site was mapped by the applicant. This map was
submitted in the bond release package along with three cross-sections.
The Division staff also surveyed the site in tday and July of 19;39 and pre-
pared a map of great similarity to the IJ.C.C. submittal.
Une series of settlement cracks were ob::erved close to the low wall. The
cracks run approximately 360' in length. There is a 3" offset on the north
end and a o" offset in a 6' wide graben•-rift structure ~ ~ ninety-seven
feet from the south end. The cracks range in depth from 8" to 56" in depth
averaging 12". Three, roughly triangul+rr setttn9 pits 4 1/2 " long, 2' wide
and 18"-24" deep were found 100'in from the north end of the crack.
Mann Draw flows through the northwest corner of the site and the entire mine
site drains towards the draw.. Four drainages deserve mention. p temporary
eyebrow ditch starts al N4466, E 3625 and runs northwest along the access
road to Mann Draw allong the original drainage on the south end of the
property. I; hasJnine rock check dams 'in it. This is fed by a small ditch
on thei'~ south and southwest side of the shop area. A 500'-600' wide
Swale in the area bounded by N5000-N6000 and E250D - E3500 also drains to
Mann Draw. A Swale formed on the north side of the East Durtrp at approximately
N 4700 and E 4000 also drains to Mann Draw.
An alternative sediment treatment control method has been employed at the site
and all ponds have been removed. Simpl;r described, ten foot wide contour
terrace benches were installed at 200' intervals or less to reduce slope
length to achieve sediment control. These terraces range in length from
350' - 240U' in length and are graded towards the slope at 2'- 4', resulting
in an overall depth of 04'. During the bond release inspection, some of the
inslopesand the grades of the contour t~arraceswwere measured. These measure-
ments follow the narrative.'~Permanent structures at the site include the
perimeter fence, 2D' wide perimeter acu~ss roads, the gravelled shop yard,
two concrete pads, the domestic well at the office, and the septic system.
Utility poles surround the property bur~io not belong to the operator.
Cunoco controls a three phased line which runs along the west side of the
